Hi guys, This morning I spent some hours of putting all the components of my PCB in the right spot. Then I saved the PCB, closed it, closed the editor and went for lunch. Now I opened the PCB again and **everything **has moved 50 mil to the left and 50 mil down, so almost everything is now off-grid. Some components were locked, some were not, makes no difference; they all moved. I'm using version 6.3.39  BR//Willem.
